BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
The Water Utilities’ 2019 capital project plan includes the rehabilitation of approximately 260 manholes, 13,000 linear feet of main line sewers and 150 sewer service laterals. The primary focus of these projects is to reduce infiltration and inflow, which is leakage of groundwater and surface water into the system.
The Water Utilities issued Bid 19-058 seeking a contractor to rehabilitate 12,826 feet of eight-inch (8”) and ten-inch (10”) diameter sanitary sewer pipeline located in the Brookdale subdivision and around Naper West Plaza. The contractor will be using no dig lining technologies to reduce cost and disruption to the community. Sanitary sewer pipeline lining is a major component of the City’s strategy to reduce system leaks associated with storm water infiltration during weather events through pipe cracks and fissures, which reduces sanitary system capacity during weather events. Lining the sanitary sewer provides a seamless, leak-free pipe to maintain structural integrity for approximately 50 years. Reducing leaks and preserving system capacity helps reduce the number and severity of sanitary sewer back-ups.
To secure the lowest possible pricing, the bid specified two competing lining technologies, glass reinforced plastic (GRP) and cured-in-place thermosetting resin pipe (CIPP).

Michels Corporation is the lowest responsive and responsible bidder. The engineer’s estimate was calculated based on previous unit prices for CIPP work.
